Hi Priscilla,
Haven't tried it but how about posting the master datawindow
rowfocuschanged event or the linkage service pfc_rofocuschanged from an
itemchanged caused by the drop-down selection.
IF DWO.Name = "dddw_column" THEN
IF IsValid ( inv_Linkage ) THEN
inv_Linkage.Post Event pfc_RowFocusChanged (row)
END IF
END IF
